U87 (Omni)
Inspired by Neumann® U87 (Omnidirecitona)
Model of: Neumann U87
type:
- capacitor
- Omni (omnidirectional)
picks up: from all directions without lateral attenuation
WHAT MAKES IT SPECIAL
compared to the other U87s:
- total environment
- maximum realism maximum space minimum focus
SOUND CHARACTER
- low very natural and full
- medium extremely realistic
- high very airy
- answer completely three-dimensional
in practice: “real room” sound, zero evident coloration, maximum realism
TIMBRIC PERSONALITY
it's a mic:
- ultra natural
- ultra space
- very open
- not very direct
perfect for: realistic clean ambient studio recording
cleanambientrecording
Controls
Axis Interaction
practically irrelevant
- ON → minimum focus
- OFF → more widespread
Gain (dB)
very sensitive
Mic Distance (inch)
- Distance 0–1”: not very useful
- Distance 1–3”: Direct but diffuse
- Distance 3–6”: natural
- Distance 6–10”: ambient
- Distance 10+: total room
Low (dB)
VERY IMPORTANT
very present bass
use:
- 0 → natural
- 1 / -2 → control
High (dB)
use:
- 0 → natural
- +1 → more air
- over → too bright
Delay (ms)
fundamental
create real depth simulate distance
Ambience (Y/N)
always ON
Amb Level (dB)
- low → natural
- medium → study
- high → ambient
Amb Size (ms)
- 40–80 → study
- 80–120 → large
Pro Tips
QUICK SUMMARY
- type: omni capacitor
- character: ultra natural / spatial
- strength: realism
- limit: little focus
ON DARK CAB (PPC, Orange)
EXCELLENT opens completely
ON MODERN CABs (VHIII, 6505)
very natural less aggressive
ON VINTAGE CAB
perfect disco sound
ON HI-FI CAB (TVX, SW Giant)
risk: → too widespread → poorly defined
PRO
maximum realism maximum space "real studio" sound perfect for layering
AGAINST
little attack, poorly defined, difficult to use alone
